摘要：In this pa.er a.simplified a.proa.h to optimize the design of Shell Tube Hea. Excha.ger [STHE] by flow induced vibra.ion a.a.ysis [FVa. is presented. The vibra.ion a.a.ysis of STHE helps in a.hieving optimiza.ion in design by prevention of tube fa.lure ca.sed due to flow induced vibra.ion. The ma.n rea.on for tube fa.lure due to flow induced vibra.ion is increa.ed size of STHE. It is found tha. in ca.e of increa.ed size of STHE, the surfa.e a.ea.a.d number of tubes increa.es, thus the understa.ding a.d a.a.ysis of vibra.ion becomes a.very difficult ta.k. a.a.n it is found tha. flow induced vibra.ion a.a.ysis is considered a. a. integra. pa.t of mecha.ica. &a.p; therma. design of STHE. The deta.led design, fa.rica.ion, testing a.d a.a.ysis work wa. ca.ried out a. a.fa.La.a. (India., Ltd., Pune-10.
